ABSTRACT
With the development of our country's economy, there are more and more automobile passenger stations. Due to the requirement of energy saving, it is more and more important to optimize the design of power supply and distribution system of automobile passenger station. In order to choose the most energy-saving way to operate passenger station. Various schemes are designed for the power supply and distribution system of a railway passenger station, the main points of the design are expounded, and the reliability is also analyzed. Automobile passenger station has the characteristics of complex structure and space, more and more functional rooms and so on. In order to ensure the safety, reliability and economy of power supply and distribution system, higher requirements are put forward for building electrical design.
In this paper, the design of electrical lighting and power supply and distribution in a passenger station is studied. The specific contents of electrical lighting and power supply and distribution design are discussed in detail, including load calculation, short circuit current calculation, illumination calculation, lighting system design, load grade determination, low voltage distribution system design, main wiring scheme of transformer distribution room, reactive power compensation, transformer selection, primary system scheme design, lightning protection grounding system design, etc. Combined with engineering cases, the electrical design of power supply and distribution system, load classification, power supply, lighting system and lightning protection device of automobile passenger station is briefly analyzed.
